I wonder whether Microdata would be beneficial to SERPs at all? Do any of you guys have experience with using it??

Schema markup, also called dependent statistics, is the language of serps, the use of a unique semantic vocabulary. it is code used to more honestly offer data to serps in order to apprehend your content

Microdata is a set of tags that aims to make annotating HTML elements with machine-readable tags much easier.

Microdata is an HTML standard, created by WHATWG, for describing rich metadata in web pages. Search engines and web crawlers can extract and process microdata from a web page and use it to provide more relevant results to users. We can think of microdata as speaking directly to search engines (Google, Bing, Yandex, Yahoo, etc.) and telling them what the page elements are, be it the author's name, a movie title, or a star rating. And then a search engine will highlight this marked-up content in searches.
